Finally, it appeared, there was a breakthrough on the practice field. In the Chiefs&rsquo; first session back in Kansas City after more than three weeks of training in Wisconsin, there was a single arrowhead sticker on one side of linebacker Mike Vrabel&rsquo;s helmet. That meant, of course, Vrabel had made the team. Coach Todd Haley had back in the spring famously ordered the arrowhead stickers removed from the helmets for practice, saying players would earn them back when they made the team.
